Sponsor Law and Legal Definition
With regard to immigration purposes, sponsor means a petitioner. A sponsor can be a U.S. citizen, U.S. permanent resident or U.S. employer who undertakes to bring an immigrant legally into the U.S. Close U.S. relative or U.S. employers who need a persons service in their businesses are the only ones with the legal ability to act as sponsors. When they do so, they are called petitioners.
Pursuant to 20 USCS § 932 (2), [Title 20. Education; Chapter 25A. Overseas Defense Dependents' Education] the term sponsor means “a person--
(A) who is--
(i) a member of the Armed Forces serving on active duty, or
(ii) a full-time civilian officer or employee of the Department of Defense and a citizen or national of the United States; and
(B) who is authorized to transport dependents to or from an overseas area at Government expense and is provided an allowance for living quarters in that area.”
